LOOSE-LEAF BOOK.

Patented Oct. 8, 1907.

Application filed October 4, 1906. Serial No. 337,374.

I To all whom it may concern:

/ side margins.

Be it known that I, WILLIAM H. GARLAND, a citizen of the United States,residing at Kansas City, in the county of Jackson and State of Missouri,have invented certain new and useful Improvements in Loose'Leaf Books,of which the following is a specification.

This invention relates to loose leaf books of that type embodying pairsof substantially semicircular hooks which interlock together at theirfree ends and are secured in such position to fasten the leaves inplace, and has for its object to produce a book of this characterwherein the hooks are locked rigidly together and can not be separatedby any pull or pressure .applied directly upon them, such for instanceas would be applied by pulling in opposite directions upon the leaves orby pulling in opposite directions upon the hooks themselves. I

Other objects of the invention will hereinafter appear, and it consistsin certain novel and peculiar features of construction and organizationas hereinafter described and claimed, reference being had to theaccompanying drawing, in which,

Figure 1, is an inverted plan view of the fastening device,-the book andclamp plate being omittedwith the hooks locked in operative or closedposition. Fig. 2, is a detail top plan view of the spring clamp plateforming a part of the fastening device. Fig. 3, is a view similar toFig. 1 but with the hooks in their inoperative or opened position. Fig.4, is a plan view of a portion of the book with the hooks in theiroperative or closed position. Fig. 5, is a vertical section taken on theline V-V of Fig. 4, with the fastening device and book cover in closedposition, the leaves being omitted. Fig. 6, is a section taken on theline VI-VI of Fig. 5 but with the hooks occupying their inoperative oropened position. Fig. 7, is a detail plan view of a pair of hooks and aplate connecting and forming journals for said hooks. Fig. 8, is alongitudinal section taken on the line VIIIVIII of Fig. 6. Fig.- 9, is aside view of the cam rod for closing the hooks and locking them in -suchposition. Fig. 10, is a cross section showing the rod equipped with amodified means for operating it. Fig. 11, is a perspective view of oneend of a channel plate forming a part of the invention.

In the said drawings, 1 indicates a channel plate provided withoutwardly projecting flanges 2 at its Near its ends tongues are stampedout of opposite sides of said plate and bent inward to form supports 3for a pair of short bearing plates consisting of arched central portions4 flanked by pairs of eyes 5 which form journals for the shortlongitudinal or body portions 6 of a pair of segmental hooks 7 whichextend through holes 8 of the channel plate. One of each pair of hooksis bifurcated as at 9 to receive the beveled or pointed end of the otheras shown most clearly in Fig. 7. The opposite ends of the body portionsof the hooks terminate in inwardly projecting arms 10, disposed side byside, it being noted in this connection that the arms 10 are so disposedbecause one of the eyes is longer than the other, as shown clearly inFigs. 1, 3, and 7.

11 indicates a rod arranged longitudinally within the channel plate 1and between and parallel with the body portions 6 of the hooks, thearched portions 4 of the bearing plates forming journals for said rod,which is held against said arched portions by the underlying arms of thehooks as shown most clearly in Figs. 1, 3, and 8, the rod beingprevented from longitudinal movement by the heads or enlargements 12,engaging the opposite edges of the bearing plates, from arms 10. V

13 indicates notches in rod 11, to receive the arms 10 of the hooks whenthe latter occupy their inoperative or open position, and to hold themyieldingly openI provide a back plate 14 bent to bridge the channelplate and form a cover for all of the parts described except the hooksand provided with stiff spring tongues 15, which tongues are the meansemployed for pressing said arms 10 up into the notches and thereby holdthe hooks yieldingly apart to facilitate the insertion or removal ofleaves of the book.

The side edges of the back plate are beveled back to form grooves 16, toreceive the flanges 2, so that said back plate can be engaged with saidflanges and slid longitudinally thereof until it completely bridges thechannel plate. For the purpose of turning the rod 11 and thereby causingthat portion of it above arms 10 to press the latter outwardly againstthe resistance of spring tongues 15 to effect the closure of the hooks,I prefer to bifurcate the end of the rod as at 17 adjacent to the rearedge of the book and pivot in said bifurcation as at 18, a handle 19,which handle after the rod is turned so as to close and lock the hooks,may be swung into the longitudinal slot 20 in the channel plate, inwhich position it fits snugly as shown in Fig. 1, and is accessiblebecause it can be swung to the position shown in Fig. 3 by engaging afinger nail with its short flange 21. 1

In the modified construction shown in Fig. 10, I show in lieu of thepivoted handle 19, a segmental handle 22 rigid with the rod 11 andprojecting slightly through the cured to the sides of the cover as at28, said leather strip being perforated as at 29 to receive the hooks.

With the parts arranged as shown in Figs. 3 and 6, the customaryperforated leaves can be slipped on or removed from the hooks, and thespring tongues 15 hold the latter open with a yielding pressure.

To secure the leaves in position the operator turns the rod half wayround so that its uncut portion originally above the arms 10, shallforce the latter downward and thus cause the segmental hooks tointerlock together, it being noticed that they are thus interlocked withan unyielding pressure and that they cannot be opened until the rod isagain turned until the notched portions 13 are disposed downward toreceive the arms 10 continuously pressed in an upward direction by thespring tongues of the back piece, it being understood of course that therod may be turned through the medium of handle 19, handle 22 or anyother suitable means.

From the above description it will be apparent that I have produced aloose leaf book possessing the features of advantage enumerated asdesirable and which may be modified in some particulars withoutdeparting from the spirit and scope of the appended claims.

Having thus described the invention what I claim as new and desire tosecure by Letters Patent, isz- 1. In a loose leaf book, a plate havingopenings and a slot at one end, a pair of hooks extending through saidopenings and adapted to interlock at their free ends and provided withparallel body portions suitably journaled and equipped with inwardlyprojecting arms, a rod extending longitudinally of said plate andsuitably journaled and provided with a cam portion overlying said armsand adapted when the rod is turned to one position to permit said armsto rise and the hooks to open and when the rod is turned part way roundto depress said arms and close the hooks, and a handle pivoted to oneend of the rod and adapted when the hooks are closed to fit in the slotin the plate and prevent turning movement of the rod.

2. In a loose leaf book, a channel plate provided with outwardlyprojecting side flanges and openings, and with inwardly projectingsupports, bearing plates resting on said supports, segmental hooksextending through said openings and provided with longitudinal bodyportions journaled in said bearing plates and equipped with in wardlyprojecting arms, a rod extending longitudinally of the plate andsuitably journaled and provided with cam portions overlying the arms ofsaid body portions. means for holding said arms upward with a yieldingpressure when the cam portions of the rod occupy their highest ptsition, and means to lock said rod against turning movement after it hasbeen turned to lower said caln portions and effect the depression ofsaid arms.

3. In a loose leaf book, a channel plate provided with outwardlyprojecting side flanges and openings and with inwardly projectingsupports. bearing plates resting on said supports and having archedmiddle portions. mental hooks extending through said openings andprovided with longitudinal body portions journaled in said hearingplates and equipped with inwardly projecting arms, a rod extendinglongitudinally of the plate and jour naled in said arched portions ofthe hearing plates, and pro vided with cam portions underlying the armsof said body portions, means for holding said arms upward with ayielding pressure when the cam portions of the rods occupy their highestposition, and means to lock said rod against turning movement after ithas been turned to lower said cam portions and effect the depression ofsaid arms.

4. In a loose leaf book, a channel plate. provided with outwardlyprojecting side flanges and openings and with inwardly propectingsupports, bearing plates resting on said supports and having archedmiddle portions, seg mental hooks extending through said openings andprovided with longitudinal body portions journaled in said bearingplates and equipped with inwardly projecting arms, a rod extendingltnigitinlinally of the plate and journaled in said arched portions ofthe bearing plates. and provided with cam portions underlying the armsoi said body portions, and with collars engaging the bearing plates.means for holding said arms upward with a yielding pressure when the camportions of the rod occupy their highest position, and means to lock therod against turning movement after it has been turned to lower said camportions and effect the depression of said arms.

In testimony whereof I allix my signature, in the presence of twowitnesses.
